1: RACK MOUNT FIXING HOLES: Allows for installation into a standard 19" rack case.
2: POWER SWITCH: Turn off amplifier when not in use.
3: VENTILATION HOLES: To keep your amplifier cool, air passes through the front panel punching, through a filter and finally
exiting to the rear of the unit.
It is vital that the flow of air IS NOT restricted in any way.
If the amplifier is rack mounted, there MUST be a free un-restricted flow of air to prevent potential overheating. There should be a
clearance of at least 20cm between the rear face of the amplifier and any other structures and a means of the exhaust air to escape.
4: LEVEL CONTROL AND INDICATORS: All amplifiers in the M-Range have dedicated Level control and Signal Level
monitors for each channel. The meter provides the following information:
Indicates the onboard protection circuit is active, thus preventing damage to the amplifier.
The onboard compressor / limiter is active and prevents overload or signal distortion.
Shows signal is present.
Indicates the amplifier is powered up and ready for use.
LEVEL CONTROL: This provides continuous adjustment from -80dB to 0dB. Set to 0dB for normal operation.
The function of the Level Control is determined by the amplifier mode set via the rear panel Mode Switch.
